Hi and welcome to devnet,

Can you explain in what way it's related to Qt ?

Maybe Qt7 ...

I can eventually try also to add an implementation variant for the function “QVariantValueHelper::metaType” (on my own).

Hi
While walking my imaginary dog, i was wondering if the
number you input "ui->values->text().toInt()"
means how many names/ages to get and you mean for it
to ask that many times, and not really create that many
dialogs ?
So like ask me 10 times
and one and the same dialog would show up 10 times ?
And each time, user press ok, it would save the data, then
show again ?
